5,744 PointsWouldn't 'Array.flat()' work instead of .reduce and .map? attempted to do it but didn't work
const users = [
{
name: 'Samir',
age: 27,
favoriteBooks: [
{title: 'The Iliad'},
{title: 'The Brothers Karamazov'}
]
},
{
name: 'Angela',
age: 33,
favoriteBooks: [
{title: 'Tenth of December'},
{title: 'Cloud Atlas'},
{title: 'One Hundred Years of Solitude'}
]
},
{
name: 'Beatrice',
age: 42,
favoriteBooks: [
{title: 'Candide'}
]
}
];
//This didnt seem to work//
let iii ;
iii = users.flat(3);
console.log(iii);
//this code was for the challenge **** Please look above
// const movieTitles = users.filter( onlyTitles=> onlyTitles.favoriteBooks
// .map( books=> books.favoriteBooks))
// .reduce((lib, book) => [...lib,...book.favoriteBooks], [] );
//
//
// console.log(movieTitles);

The task here is to get attributes from the objects of the array, which is not what "flat" does.

5,744 PointsNote: it would say that '.flat is not a function', I also tried with the depth being 'infinity'
